Overview
Setting up and maintaining Linea nodes from scratch is a time-consuming and resource-intensive process. For instance, running full or archive nodes requires considerable bandwidth, significant computational power, and high storage capacity. Additionally, nodes are chain-specific, meaning you need to run and maintain a separate one for each network you interact with. As such, the associated costs and complexities can quickly escalate, particularly when building cross-chain projects. Fortunately, you can avoid these challenges by using a node provider like Moralis!
At Moralis, we simplify the process of running Linea nodes by managing the underlying infrastructure and complexities for you. This allows you to set up a free RPC node on Linea with just the click of a button. To learn more about how this works, follow along with us in this guide. Let’s get started!
What is Linea?
The Linea mainnet, launched in 2023, is a zero-knowledge (ZK) layer-2 (L2) scaling solution for Ethereum. It aims to enhance scalability and flexibility for decentralized applications (dapps), creating a favorable environment for both end users and developers alike!
So, why should you build dapps on Linea?
Ease of Use: Linea is fully EVM-equivalent, simplifying the migration of existing Ethereum dapps and smart contracts to the network. Additionally, it supports popular development tools, frameworks, and languages, including MetaMask, Truffle, and Solidity, providing developers with a seamless experience. Cost Efficiency: Linea leverages ZK-rollup technology to lower transaction fees, making it a more economically friendly alternative for developers and users than Ethereum. This efficiency is especially favorable for dapps with large user bases and high transaction volumes. Scalability: Designed to handle more transactions per second than Ethereum, Linea enhances network scalability. This capability makes it an excellent choice for dapps requiring high throughputs, such as decentralized exchanges (DEXs) and games.
Now that you have an overview of Linea let’s delve into the specifics of Linea nodes!
What are Linea Nodes?
Linea nodes are computers, servers, and other devices that participate in the network by performing various key tasks required to maintain the blockchain. These include transaction validation, block propagation, data storage, and much more. The blockchain consists of many nodes that collectively contribute to Linea’s decentralization and security!
So, what exactly are Linea nodes used for?
Linea nodes have several use cases, and below, we’ll explore three examples:
Transaction Validation: Linea nodes are responsible for validating transactions and adding new blocks to the blockchain. This critical function ensures the network remains secure and operational. Data Storage: Certain Linea nodes maintain a comprehensive record of the blockchain’s transactions and smart contract data. These nodes continuously update their information with every new transaction processed on the Linea network, ensuring the data remains current and accurate. Dapp Development: Linea nodes are used to both read and write blockchain data. As such, they are essential components for building dapps and other Web3 projects.
This overview of Linea nodes outlines their essential functions. Next, we’ll guide you through the easiest way to run Linea nodes!

That’s it! Running Linea nodes is straightforward with Moralis!
Tutorial: How to Call Your Linea Nodes
Having learned how to run Linea nodes with Moralis, we’ll now show you how to make RPC calls to your node using ethers.js. Specifically, we’ll demonstrate how to fetch the native balance of any Linea wallet!
Before we start, ensure you have the following set up:
Once you have these ready, follow the steps below:
Step 1: Open your preferred IDE, create a folder, and initialize a new project using this terminal command:npm init Step 2: Install ethers.js with the following terminal command: npm install ethers Step 3: Add “type”: “module” to your ”package.json” file:
Step 4: Create a new index.js file and add the following code:import { ethers } from “ethers”;
const provider = new ethers.providers.JsonRpcProvider(“YOUR_NODE_URL”);
const address = “0x2898730f10411D6E92cad809e78cc3a7Ea82C695”;
const balance = await provider.getBalance(address);
console.log(“Balance: “, ethers.utils.formatEther(balance)); Step 5: Replace YOUR_NODE_URL with one of your Moralis node URLs and configure the address parameter to fit your query:
Step 6: Open a new terminal, navigate to the project’s root folder, and run the following command to execute the script:node index.js
In return for running the code, you will receive the native balance of the specified wallet, which will be displayed in the terminal. It should look like this:
Balance: 0.008670621126214844
Congratulations! You now know how to make RPC calls to your Linea nodes!

Limitations of Nodes
Nodes are crucial for interacting with blockchain networks like Linea. However, they are not ideal for querying and integrating on-chain data into dapps. Here are three key reasons why:
Chain-Specific: Nodes are chain-specific, meaning they are tied to a certain network. This means you’ll need to run a separate node for every chain you’re interacting with, which can become costly and time-consuming if you’re building cross-chain projects. Complex: Nodes do not support straightforward data queries such as, “What tokens does wallet X hold?” Obtaining such information often involves multiple requests and manually piecing the data together, which complicates the process. Raw Data: Nodes provide raw data that needs to be decoded, interpreted, and formatted before it becomes useful. This additional processing adds to the complexity and effort required to build dapps.
But how can we address these limitations?
A better solution for querying on-chain data is to use Moralis’ Web3 APIs. With our industry-leading interfaces, you can easily access decoded and comprehensive data with just a few lines of code. Join us in the next section to learn more about how Moralis can streamline your data integration process!
